RAILWAY-CROSSING.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed January 3, 1918. Serial No. 210,159.

To all whom it may concern.

Be it known that I, DANIEL L. AMERMAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Railway-Crossings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in railway crossings and more particularly to a bridge member therefor, the object being to provide bridge members for the intersecting tracks which are adapted to be engaged by the flange of the wheel so as to lift the tread of the wheel over the track arranged at right angles thereto, whereby jolting and jarring will be eliminated.

Another object of my invention is to provide a bridge crossing in which the bridge members are arranged within the grooves of the intersecting tracks and so mounted that they are normally held flush with the tread of the rail.

Another object of the invention is to provide a bridge crossing which is so constructed that the same can be readily placed in position in the grooves of the rails of an ordinary street car crossing in order to provide means for carrying the wheels over the intersecting tracks smoothly, thereby eliminating the shock caused by the wheels engaging the intersecting tracks.

Other objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings Figure 1 is a top plan view of an ordinary street crossing showing the application of my improved construction of bridge members thereto.

Fig. 2 is a section showing the bridge member in normal position taken on line 22 of Fig. 1.

Fig. 3 is a similar view showing the flange of the wheel in engagement with the bridge member so as to elevate the tread of t e wheel.

Fig. 4c is an enlarged section showing a spring supporting the bridge member; and

Fig. 5 is a section through one of the bridge members.

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawing 1 indicates a crossing of the ordinary construction formed by the intersecting grooved rails 2. Mounted within the grooves of the inter-rails at each corner of the crossing is a cross shaped bridge memher 3 the arms of which extend at right angles to each other and normally lie in the grooves of the tracks. These arms taper toward the central curved portion 4, forming a bridge which is adapted to receive the flange of the rail so as to lift the tread in order to carry the same over the rails arranged at right angles thereto.

Two of the arms of each bridge member are provided with depending bolts 6 which are slidably mounted in bores 5 formed in the bottom of the rails forming the crossing, said bolts carrying nuts 7 and coil springs 8 for normally holding the bridge portion at sulistantially flush with the tread of the rai s.

The cross shaped bridge members when arranged within the grooves of the tracks of the crossing as shown, prevent the bridge from moving by the thrust of the wheels and by mounting the same on springs they are normally held in position as shown in Fig.2. From the foregoing description it will be seen that I have provided a bridge crossing in which the bridge members are movably mounted within the grooves of the rails of the crossing which are normally held flush with the tread of the rails so as to close the grooves, said members yielding when engaged by the flange of the wheel so as to reduce the shock and by the particular construction of these members the wheel is carried over the crossing without jolting.

While I have shown in the drawings a movable bridge member for carrying the wheel over the intersecting tracks I do not wish to limit myself to the use of any particular construction of bridge member, as the bottom of the rail can be provided with a raised portion having inclined faces for lifting the tread of the wheel as it passes over the same, up above the track arranged at right angles thereto 50 as to reduce the shock without departing from the spirit of my invention.

I claim:

1. The combination with a crossing formed of grooved intersecting tracks, of a cross shaped bridge member arranged Within the grooves of the intersecting tracks and springs supporting said bridge member flush with the tread of said tracks.

2. A railway crossing having grooved intersecting tracks, a cross shaped bridge member mounted Within the grooves of said tracks, -"rhe arms of said bridge members have incline faces, bolts carried by said arms extending through said tracks and springs mounted on said bolts :tor holding said bridge members in raised position.

3. A railway crossing having bridge members mounted in the grooves of the intersecting tracks, said bridge members having arms arranged at right angles to each other provided with incline faces and terminating in the curved central portion, and springs for supporting said bridge members within the grooves of said tracks.

In testimony whereof I hereunto aflix'my signature in the presence of two witnesses.

DANIEL L. AMERMAN.
